1 'My invention relates to machinists? ham-- more and especially to those known as lead hammers. It particularly-seeks to provide an attachment bywhi'ch a machinists ordiiiaryrhard. head hammer may be rendered fit for use as a softzliead fhammer whereby the V same may be employedin hammering or tapf ping shafts or. pipes-having threads.

its object to provide an attachment which may collar in which; is mounted the soft metal striking element or plug, the collar being so held on the hammer head that itinay be re moved and replaced at will.

V ence'being had'to theaccompanying draw- Other objects will, in part be obvious and i p in part be pointed out hereinafter. I J i To the attainment of the aforesaid objects and ends the invention stillfurther resides in" the noveldetails of construction, combination and arrangement of parts,;all' of 'wliich'will' be Ifirstfully described in the following .de-

tailed description, then be particularly pointed out in theappended claims, refering', in which i v V Figure l is a perspective view of a hammer with my invention applied;

Figure 2 is'a side elevation of the hammer :being shown in 1verticalglongitudinal section of Figure 2.

Figure 3 is a horizontal section on the line Figure 4 is, a similar section of a modification.

'In the drawing, in which like'numerals of reference indicate like parts in all of the fig ures, 1 represents the hard heahd'of amachinplaced. I T V 1 The attachment comprises a collar 4 which may be cut. from a section of pipe, the collar having apin hole 5 through which a cotter pin 6 may be inserted. Within the collar 4 is locatedthe p1ug9 offsoftmetal such as I by simply unhooking the spring wane s: TIT-145 5 L1aa,,,bas pageant sea held. in placeby thecotter pin 6..

the pin position against accidental separation.r-

Of course, wheii is desired to remove j the plug 9 from the collar this can be done the cotter pin '6 and T a; r

by simply withdrawing driving the V plug out. i

In practice,the collar-fits overtheend Y 3. ofi-theahaminer with the plug 9 in contact with the striking face; of the hammer end, in which; position it is held against a ccidental dropping off bymeans of a coil spring ,7- that is looped around the handle Qandhas its ends 8 hooked into the eye of'thecotter pin 6.- Of course, anyother suitable elastic I member 7-may be employed for the purpose.

' When-it is desired to usethehammer for tapping threads all that is necessary is, to

place the .collar 4 with end 3 of the hammer, around the hammer and the cotter pin 6. Whenit is desired again, to use the hammer inth'e ordinary Way it is a simple matter to'removerthe attachment, 7 and slip-;

loop the spring 7 ping 0E the collar. 7 V T a From the foregoing description, taken in connection with the accompanying drawing, it is thoughtthe'construction, operation and advantages of {the invention will be clear to its plug 9 over the v I 80 i v connect its endsgto those skilled, in the art to which it relates. 7

My invention, as will liave'been seen, is really an improvement for. machinist ham mers such as mechanics use, and I call it a quick attachable soft metal hammer, face. I

The combination of metal-material used in,

lead or copper or brass'alloy or babbitt, or by mixing some of these metals together to my invention can be made up: by using solid ice 1 r ends secured to said c0tte1t p in..

produce a Wearing-material for mechanical r 7 use as a soft metal hammer. I,

What I claim is:

1. In combination with a lianimer having I ahead with an elongated striking end, of a collar fitted over said end, a metal striking plug in said collar, a cotter pinpassing 7 throughgianfaperture in said collar-with its: tangs iinbeddedin said plug, a'nda coil;
